GRID FOR OPENERS, SCUTCHERS, AND THE LIKE MACHINES.

To all whom it may concern:

Be it known that I, RoBER'r SCHAELLI- BAUM, citizen of Switzerland,residing at Providence, Rhode Island, United States of America, haveinvented new and useful Improvements in and Connected with Grids forOpeners, Scutchers, and the Like Machines.

This invention relates more particularly to improvements on an inventionfor which Letters Patent No. 447,365, March 3rd, 1891, have been grantedto me and in which a comb with metal knife-edged foundation is employedin combination with a grid and beater. Hitherto the said foundation hasbeen flat in section and its sides quite plain which made the drillingof the holes for the reception of the pins atthe required acute angle tothe foundation very difiicult.

The object of my present invention is to provide means whereby thedrilling of the said pin holes in the comb foundation is rendered mucheasier and possibleat an acute angle to the general surface thereof thanhitherto has been the case and at the same time the action of the combis improved in connection with means for supporting and securing thesaid comb. I attain these objects by the means illustrated in theaccompanying drawing, which represents a cross section of a comb andsupport constructed in accordance with my invention.

In carrying out my invention and referring to the drawing I form the topedge a of the comb foundation 6 as usual knife-edged, while instead ofleaving each side plain, I provide same with corrugations c. In everyalternate side of these corrugations I drill a row of holes passingthrough the opposite corrugation side 0 on the other side of thefoundation as near at a right angle to the said sides as possible, whichholes serve for the reception of the comb pins d securely driven intothe same. To facilitate the fix- Specification of Letters Patent.

ing of the said pins at a very acute angle to the general surface of thecomb, I may form the said corrugations slightly displaced in relation toeach other as shown. By preference I form the said corrugations angularin section and the sides through which the pin cl passes narrower thanthe others to prevent the lodging of any fibers in the corrugations.

The corrugations in the topof the foundation render the action of thecomb pins also more effective as they retain the fibers under treatmentto a certain extent, that is to say, they are caused to pass slowerthrough the pins 61 which gives the draft created by the beater moretime to free them from impurities.

The comb described is secured, say by screws 7 to an angle iron 0,whichon the top is corrugated to correspond with and engage in thecorrugations at the back of the comb foundations b and thereby renderthe comb very secure on the angle iron 0 besides preventing the pins dwhich might come loose from dropping or falling out.

I claim:

In an opener, scutcher and the like machine, in combination with abeater and a grid, a fiat stationary comb comprising a metal foundation,having corrugations in both sides, pins through every two alternateopposite sides of the said corrugations at a right angle thereto and asupport having a fiat corrugated surface in which the corrugations atthe back of the said comb foundations engage, all substantially as andfor the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
